Planning for a house move - MN collective wisdom please?

DH and I have just had an offer accepted on what is a bit of a dream house - we're moving from our mid terrace to a beautiful stone build with a huge garden and it's crazy exciting. And daunting!

So, what do we need to do to make it the most efficient move ever? Last time we moved from rented, so it was a bit different. This time around, we have a 15 month old climber, a place that hasn't been decorated since 1982, and two busy jobs.

If there's stuff we can sort in advance (phones, broadband etc) I'd love to. If anyone has a house moving spreadsheet of glory, I want to see it. And what utility deals should we be looking for? It'll be a real stretch at first so economy is key.
